Claims (2)

1 . An applying unit configured for being connected to a printer to apply an adhesive to a recording sheet, the applying unit comprising: a roller configured to transport the recording sheet that is discharged from the printer; a sensor disposed between the printer and the roller, and configured to detect a bend of the recording sheet; an applier configured to apply the adhesive to the recording sheet transported by the roller; a pressor disposed on a transport path of the recording sheet between the printer and the roller, and configured to bend the recording sheet; and a control device configured to adjust a rotation speed of the roller according to a value detected by the sensor and configured to determine the bend of the recording sheet based on the value detected by the sensor, wherein when the value detected by the sensor is equal to or greater than a bend determining value, the control device increases the rotation speed, and when the value detected by the sensor is less than the bend determining value, the control device slows down the rotation speed.
2 . An applying unit configured for being connected to a printer to apply an adhesive to a recording sheet, the applying unit comprising: a roller configured to transport the recording sheet that is discharged from the printer; a sensor disposed between the printer and the roller, and configured to detect a bend of the recording sheet; an applier configured to apply the adhesive to the recording sheet transported by the roller, the applier including a holder configured to hold the adhesive such that the adhesive faces the recording sheet, and a pressor configured to press the holder toward the recording sheet; and a control device configured to adjust a rotation speed of the roller according to a value detected by the sensor and configured to determine the bend of the recording sheet based on the value detected by the sensor, wherein when the value detected by the sensor is equal to or greater than a bend determining value, the control device increases the rotation speed, and when the value detected by the sensor is less than the bend determining value, the control device slows down the rotation speed.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application is based upon and claims the benefit of priority of Japanese Patent Application No. 2022-037735, filed on Mar. 11, 2022, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD A certain aspect of the embodiment is related to an applying unit. BACKGROUND There are printers that are known to include a printing part that prints on a recording sheet and a transfer part that transfers an adhesive to the recording sheet. RELATED ART [Patent Document 1] Unexamined Japanese Patent Application Publication No. 2020-019582[Patent Document 2] Unexamined Japanese Patent Application Publication No. 2014-097851[Patent Document 3] Unexamined Japanese Patent Application Publication No. 2011-235595[Patent Document 4] Unexamined Japanese Patent Application Publication No. 2001-018478 BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a perspective view of a printer to which an applying unit according to the present embodiment is attached; FIG. 2 is a side view of the printer to which the applying unit is attached; FIG. 3 is a side view illustrating an internal structure of the printer; FIG. 4 is a perspective view illustrating an internal structure of the applying unit; FIG. 5 is a side view illustrating an internal structure of the applying unit; FIG. 6 is a front view illustrating an internal structure of the applying unit; FIG. 7 illustrates an example of an output waveform of a sensor; FIG. 8 illustrates an example of a functional configuration of a control device; FIG. 9A illustrates an example (1) of the operation of the applying unit; FIG. 9B illustrates an example (1) of the operation of the applying unit; FIG. 10A illustrates an example (2) of the operation of the applying unit; FIG. 10B illustrates an example (2) of the operation of the applying unit; FIG. 11A illustrates an example (3) of the operation of the applying unit; FIG. 11B illustrates an example (3) of the operation of the applying unit; FIG. 12A illustrates an example (4) of the operation of the applying unit; FIG. 12B illustrates an example (4) of the operation of the applying unit; FIG. 13A illustrates an example (5) of the operation of the applying unit; FIG. 13B illustrates an example (5) of the operation of the applying unit; FIG. 14A illustrates an example (6) of the operation of the applying unit; and FIG. 14B illustrates an example (6) of the operation of the applying unit. SUMMARY Assuming that a printer has no part for transferring an adhesive, it is conceivable to retrofit a transfer part to the printer and transfer an adhesive to a recording sheet that has been printed. However, retrofitting a transfer part to a printer is not an easy task and requires complex control. Therefore, there is a demand for an applying unit that can be retrofitted to various printers without necessitating complex control. According to one aspect of the present disclosure, an applying unit that can be connected to a printer and apply an adhesive to a recording sheet includes: a roller configured to transport the recording sheet that is discharged from the printer; a sensor configured to detect the bend of the recording sheet; an applying portion configured to apply the adhesive to the recording sheet; and a control device configured to adjust the rotation speed of the roller according to the value detected by the sensor. DESCRIPTION OF EMBODIMENTS Hereinafter, a description will be given of an embodiment of the present invention with reference to the drawings. Now, a non-limiting example embodiment of the present disclosure will be described with reference to the accompanying drawings. Throughout the drawings, the same or corresponding members or parts will be assigned the same or corresponding reference numerals, and overlapping description will be omitted. Now, an example of a printer to which the applying unit of this embodiment is attached will be described with reference to FIG. 1 to FIG. 3. A printer 10 is, for example, a thermal printer, and is installed in an ATM (Automated Teller Machine), a ticket vending machine, a kiosk terminal, or the like. However, the type of the printer is not limited to a thermal printer, and other printers such as an inkjet printer and a laser printer may be used as well. The printer 10 has a thermal head 11, a platen roller 12, a motor 13, a movable blade 14, a fixed blade 15, a frame 16, and a control substrate 17. The printer 10 sandwiches a recording sheet P between the thermal head 11 and the platen roller 12, and prints on the recording sheet P by feeding the recording paper P by the rotation of the platen roller 12, and by pressing the recording sheet P against the thermal head 11. The motor 13 rotates the platen roller 12. The movable blade 14 and the fixed blade 15 constitute a cutter, and the recording sheet P is cut by moving the movable blade 14 toward the fixed blade 15. The control substrate 17 is attached to the frame 16. The control substrate
